ROY I1. WILLIAMS, F MCKINNEY, TEXAS.

COTTON-CHOPPER ATTACHMENT FOR GULTIVATORS.

To all whom it may concern:

Be it known that I, ROY L. WILLIAMS, a citizen of the United States,residing at Mc- Kinney, in the county of Collin, State of Texas, haveinvented certain new and useful improvements in Cotton-ChopperAttachments for Cultivators; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in attachments for Cultivators,and has particular reference to a cotton chopping attachment therefor.

The principal object is to provide a simple device of this characterwhich may be quickly and easily attached to the frame of the ordinarycultivator, said device being adapted not only for chopping cotton, butcan be used for chopping out weeds when cultivating the standing plants.

Another object is to provide a simple device of this character which isoperable from the drivers seat.

Other objects and advantages will be apparent from the followingdescription and with particular reference to the accompanying drawings:

In the drawings: Figure 1 is a side elevation of a cultivator showing mydevice applied thereto, Fig. 2 is a top plan view, Fig. 3 is a rearelevation, Fig. 4 is an enlarged fragmentary detail of the attachment,Fig. 5 is a vertical transverse section 011 the line 55 of Fig. 2. Fig.6 is a top plan view of one of the clamps 12.

Referring particularly to the drawings, a cultivator is shown which hasa frame i11- cluding the longitudinal side bars 10, the arch brace 11 atthe forward portion thereof, and the inner frame having the side membersto which my chopping attachment is removably secured. Secured to theside members 10 of the inner frame are the clamps 12. Slidably mountedon the upper side of each of the clamps 12 is a plate 31 having alongitudinal series of openings 32 for registry with an opening in across member 34. A pin 35 is passed through the registering openings,said pin having a pivoted latch member 36 carried by the clamp engagedin the hooked end 37 to hold the pin from dropping out of place.

r The inner end of the plate 31 carries a ver tical pin 26 which isarranged to be re- Specification of Letters Patent.

ceived in the perforated head 27 on one end of a transverse link or arm13. The link is formed with a central longitudinal slot 15 across whichis disposed a pin 16. Extending vertically through the slot, and pivotedon the pin 16, is a lever let, the lower end of which has securedthereon a hoe blade 17. It will be noted that by means of the pin 86carried by the plates 31 and support 34, the clamps can be adjustedtoward and away from each other to adapt the device for attachment tocultivators in which the side bars are greater or lesser distancesapart. Secured transversely of the frame and to the arms of the beforementioned brace 11 is a bar 18. Loosely connected to the bar 18 is abrace bar 19, the opposite end of which is loosely connected to thelever 14 and is provided intermediately with a turn buckle 19 so thatthe same may be adjusted to hold the hoe lever in proper verticalposition. Pivotally attached. to the transverse bar 18 is a lever 20which extends rearwardly, and is connected by the universal joint 21 tothe upper end of the hoe lever, the rear end of the said lever beingcurved in the manner shown at- 22, and formed with a series of rackteeth 23. Pivoted on the rear end of the lever is an adjusting lever 21, having a suitable handle 25 on its rear extremity, and a springpressed pivoted pawl 25 for engagement with the teeth of the racksegment, whereby the handle lever may be properly adjusted according tothe height of the drivers seat.

The hoe lever is so arranged as to extend down between the regularcultivator shovels, 27, so that when it is desired to chop out anyparticular plants or weeds, the handle lever 24: is depressed and thrownto one side to bring the hoe blade into engagement with the plant to bechopped out, said lever having a horizontal swinging movement on itspivot, and a vertical movement by means of the elongated slot formedtherein, thus making it possible to swing the device to one side and upout of engagement with the ground.

It will thus be seen that the device is simple, and the chopping of theplant under the complete control of the operator, making it possible tohoe out the weeds while cultivating the plant.

What is claimed is:

1. The combination with a cultivator having an outer frame and an innerframe said inner frame including side bars, of a cotton choppingattachment therefor comprising an arm adjustably connected at its endsto the said side bars, a chopping hoe pivotally carried centrally on thesaid arm, a transverse member secured to the frame in advance of thehoe, an adjustable brace swiveled to the hoe and to the said transversemember, a lever pivotally attached at one end to the transverse memberand loosely attached to the hoe, and a handle on the lever for movingthe same, whereby the chopping hoe is capable of being simultaneouslyraised or lowered and swung laterally.

2. A cotton chopper attachment for cultivators comprising a verticallever carrying a hoe blade, an arm pivoted to the lever, clamps on theends of the arm for detachable engagement with the side bars of thecultivator, each of said clamps comprising a clip, a plate secured tothe clip, a perforated plate slidable on the clip, an aperturedsupporting cross member on the plate for guiding the perforated plate, apin for engagement in the aperture of the cross member, said pin beingprovided with a hook, and a pivoted latch carried by the cross bar, forengagement with-the hook to hold the said pin in position.

In testimony whereof, I aflix my signature, in presence of twoWitnesses.
